Signal is the physical quantity that represents the message, and in the field of transmitters, such as pressure transmitters, liquid level transmitters, temperature transmitters, temperature and humidity transmitters, and differential pressure transmitters, analog signals are used to collect and process data. Advantages of analogue signals: The main advantage of analog signals is their precise resolution, which has a higher information density compared to digital signals. Its signal waveform changes with the change of information, and its characteristic is that the amplitude is continuous (the meaning of continuous is that an infinite number of values can be taken within a certain value range), and because there is no quantization error, it can describe the true value of physical quantities in nature as close as possible. Another advantage of analog signals is that analog signal processing is simpler than digital signal processing. The processing of analog signals can be achieved directly from analog circuit components (e.g., operational amplifiers, etc.). Disadvantages of analog signals: The anti-interference ability of analog signal is poor, and the signal will be interfered by various noises inside the external communication system during the transmission process along the line, and it is difficult to separate the noise and signal after mixing, so that the communication quality is reduced. The longer the line, the more noise accumulates. The confidentiality of analog signals is also poor, especially microwave communication and wired communication, which are easy to eavesdropping. As long as an analog signal is received, it is easy to get the content of the communication. Of course, there are also measures to reduce and avoid the above problems of analog signals, and we can use ground shielding, good line contact, using coaxial cable or shielded twisted pair, or even optical fiber, which can alleviate these negative effects to some extent.
